# Scan QR vs SD

The clearest difference is in-app purchases: SD at none against Scan QR's 2. SD also leads on ads (none vs shown) and iOS requirement (13.0 vs 17.0). Scan QR's advantage is update cadence (daily vs every 2 months). On price and device support there is nothing between them.

Both are free to download. Scan QR sells 2 in-app purchases, starting at $1.99 per 7 days. SD asks for nothing beyond the download.

Scan QR ships an update daily, SD every 2 months. The most recent releases landed on October 7, 2026 and October 13, 2026 respectively.
